       <STRONG>int</STRONG> <STRONG>set_menu_pattern(MENU</STRONG> <STRONG>*</STRONG><EM>menu</EM><STRONG>,</STRONG> <STRONG>const</STRONG> <STRONG>char</STRONG> <STRONG>*</STRONG><EM>pattern</EM><STRONG>);</STRONG>

</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       Every  menu  has  an  associated pattern match buffer.  As input events
       that are printable characters come in, they are appended to this  match
       buffer and tested for a match, as described in <STRONG><A HREF="menu_driver.3x.html">menu_driver(3x)</A></STRONG>.

       The  function  <STRONG>set_menu_pattern</STRONG>  sets  the pattern buffer for the given
       menu and tries to find the first matching item.  If it  succeeds,  that
       item becomes current; if not, the current item does not change.

       The function <STRONG>menu_pattern</STRONG> returns the pattern buffer of the given <EM>menu</EM>.


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       The  function <STRONG>menu_pattern</STRONG> returns a pointer, which is <STRONG>NULL</STRONG> if the <EM>menu</EM>
       parameter is <STRONG>NULL</STRONG>.  Otherwise, it is a pointer to  a  string  which  is
       empty if no pattern has been set.  It does not set <STRONG>errno</STRONG>.

       The function <STRONG>set_menu_pattern</STRONG> may return the following error codes:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or out-of-range argument.

       <STRONG>E_BAD_STATE</STRONG>
            Routine was called from an initialization or termination function.

       <STRONG>E_NOT_CONNECTED</STRONG>
            No items are connected to menu.

       <STRONG>E_NO_MATCH</STRONG>
            Character failed to match.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno(3)</STRONG>).

       These routines emulate the  System  V  menu  library.   They  were  not
       supported on Version 7 or BSD versions.
